I know build new account for his isn't very hard task and I believe he will do that. Perhaps we will not able to identify or we will not bother on it, but I wouldn't like to believe he will leave this forum for forever. Before leave forum blame to a members wasn't wise decision in my opinion instead of mention won mistakes.
However, I believe he should try to avoid this kind of behavior if he come back with other account or real life as well. He have lack of patience and ego is too high and both is harmful for a human.
